WINDQW CHANNEL.

Application led October 4, 1988. Berialjo. 592,867.

To all fwhom t may concern.

Be it known that I, ERNEST M. GrU'iL` LAUME, a citizen of the United States, residing at W'orcester, in the county of Worcester and State of Massachusetts, have invented certain new and useful Improvements in `Window Channels, of which the following is a specification.

My invention relates to an improvement in window channels, and more particularly to a device of this character made jof textile fabric, such as felt.

A device of this character has been made of a single strip of felt bent to form a channel. My improved channel is made of several strips offelt, stitched or otherwise secured together, and fashioned into a channel and fastened in that shape. This may be made in various forms.

In the accompanying drawings: Fig.1i's a view of the strip from which the channel is made;

Fig. 2 is an enlarged cross-section;

Fig. 3 is an end view of the completed channel;

Fig. 4 is a similar view showing it in a window frame with the two sides faced with a thin fabric, such as felt;

Fig. 5 is an end view of a slightly modified form of strip shown flat;

Fig. 6 is a similar view with the sides bent to form the channel;

Fig. 7 is an end view of still another form shown flat;

Fig. 8 is a view of the same with the sides turned to form the channel;

Fig. 9 shows the same applied to a wlndow frame and Fig. 1() illustrates still another possible form.

The numeral 1 represents a backing strip, preferably of felt 'of' suitable width and thickness; and 2, 3, and 4 are narrow bearing strips of felt fastened securely` thereto by rows of stitches 5 or otherwise, and spaced apart lengthwise of the strip to form longitudinal channels 6. These channels are just wide enough to permit the edges -to be folded to fold the sides as viewed in Fig. 3, with the inner edges 7 of the strips 2 and 4 resting upon the o the intermediate stri 3. en bent into this` form, the device is held in shape b the stitches 8 crossing the corners, as s own in Fig. 3, thus forming the permanent chanosite sides of' nel 9 at the center in which the plate-glass or window W slides.

In Fig. 4, a facing 10 of thin felt or other fabric is shown folded around the sides and held by stitches 11. 'This facing may be used or not, accordingl as desired. In Fi g. 4, the window channe is shown in position in the groove 12 of the windowframe 13.',

In Fig. 5, the ends 1 of the main strip are extended and folded over and held by stitches 14, thus making the sides of a sin le piece with the back of the channel. 'Iie central strip 3' is-a separate strip held by stitches 5' as` before. This form of channel is Shown completed in Fig. 6.

In carrying out the invention, it would be quite possible to make a broad back strip 1" suiciently wider so that the edges could be folded over toenclose the narrow side strips 2" and 4", thus saving the necessity of using an extra strip for facing or lining.

A window channel of this character may be manufactured economically, for the reason that comparatively narrow strips of felt may be used; and, furthermore, for the reason that there is no waste in the formation of the channel. Furthermore, no special machinery is required to manufacture -it, as the strips composing it '(if stitched) may be securely attached by an ordinary sewing-machine.

I claim: Y

1. A window channel comprising a flexible backing strip having a finished face, central and side bearing strips having finished faces and edges superimposed u on said backing strip and formingspaces Ibetween bearing strips, the backing strip adapted to bend at the spaces to impose a finished `edge of one bearing strip against the finished face of one ad'acent bearing strip to form a channel of uniform qualities of strength due to the use of finished strips of material.

2. A window channel comprising a backing strip, central and side bearing strips superim osed thereon and having spaces between a 'scent bearin strips, so arranged that ben ing the backing strip to form the channel laces the bending strain solely on the backing strip and completel closes the spaces by imposing an edge o a bearing stri" against the face of an adJacent strip to un s channel, the bearing surfaces of lll which are' of substantially uniform qualities of resilience.

3. A Window channel comprising a backing strip, a central bearing strip superimposed thereon. side bearing strips carried by the lim-kiwi, strip and spaced from the central strip, the bearing` surfaces being substantially in the same plane and so arranged that, bending the backing: strip to form the channel places bending strain solely on the backing strip and completely closes the spaces by imposing an edge of one strip against the face of an adjacent strip to form a channel, the hearing surfaces of which are of substantially uniform qualities of resilience.

4. A window channel including four strips of material, one of which is relatively wide and thin, and the othei three superimposed thereon with spaces between their adjacent edges. the outer edges of the wider backing strip folded around the outercdges of the narrow superimposed stripsl aud brought approximately to the inner edges thereof, and lines of stitching through the adjacent edges of the superimposed strips and extending through the Wider' backing strip. and stitchingr through the eoruers'ot the channel for holding the latter in form.

In testimony whereof I afiix my signature.
